Allow EteServer User Signup Through My Frontend Application only, disallow publicly.

[SHoward-A]

I want to allow signup users in eteserver, but I do not want anyone else to allow this (I mean do not publicly allow, except my front end application ). What I have in mind is that I will create new custom sign up API, and use some signature to make sure request is coming from my front end application. After that verification, I want to signup user, I am not sure how to do this, I tried to explore etebase python sdk so that I can replicate functionality from there, but no luck.

Can anyone please guide, how I can achieve this thing. Thanks in advance -:)

Use a proxy and only allow the client's IP address. You can also use a cookie which is set by your proxy, then block all attempts to signup, which do not include this cookie. All of this can be done with Nginx

At the end of the day though, it's fragile, as it trusts the user agent. There really isn't a way to do it other than playing cat-and-mouse games with people trying to circumvent it.
